I'm interrested in trying to improve the performance of a GNU-based C++
compiler. One option that I'd like to explore is precompiling the headers
like many of the PC vendors do. Does anyone know of some public-domain
code to do this? Is there any written material describing how this is
typically accomplished (I can see that ifdefs and macro definitions will
need special treatment)?

Thanks for any information you may provide,
